GeForce GTX 560 Ti 448 vs GeForce GTX 570

Intro

Compare those specifications to the GeForce GTX 570, which has a GPU core clock speed of 732 MHz, and 1280 MB of GDDR5 RAM running at 950 MHz through a 320-bit bus. It also is made up of 480 SPUs, 60 Texture Address Units, and 40 ROPs.

GeForce GTX 560 Ti 448		144000 MB/sec
	Difference: 8000 (6%)

Texel Rate

The GeForce GTX 570 will be a small bit (about 7%) better at AF than the GeForce GTX 560 Ti 448. (explain)

GeForce GTX 570		43920 Mtexels/sec
GeForce GTX 560 Ti 448		40992 Mtexels/sec
	Difference: 2928 (7%)

Pixel Rate

Both cards have the exact same pixel fill rate, so theoretically they should be equally good at at full screen anti-aliasing, and be capable of handling the same screen resolutions. (explain)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of information (counted in MB per second) that can be transferred over the external memory interface within a second. The number is calculated by multiplying the bus width by the speed of its memory. If it uses DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This is calculated by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
